Normal service, I have been using for more than one year, everything that I purchased worked fine, even if there was a marriage, they quietly make an exchange. Normal adequate operators, and an adequate seller in the store. So thanks Satel
If you bought a thing from them and it works fine, then you are lucky, and if there is some kind of factory defect, you will have to spend a lot of your nerves, effort and time in order to prove it and get your money back, in general, I do not advise you to take risks.
